I’ve heard of muscle wire that contracts in length (about %) when And whats the difference between Flexinol and Nitinol? or is this a. If you’re using SMAs for the first time, I recommend starting with Flexinol muscle wire (which is available on Robotshop, or directly from. Flexinol LT Muscle Wire These unique nickel-titanium alloy Muscle Wires actually shorten in length when electrically powered, and can lift thousands of.

How-To: Work with Shape-Memory Alloy | Make:

See more product details. By adding simple folds, you can change a mechanism completely. You want to give it enough for a dramatic effect, but not so much current that the wire burns out and stops contracting. So I changed my major to mechanical engineering because they get access to the machine shop! Much of the remainder of this article will be concerned with addressing these challenges. Flexinol and Muscle Wires are both trademarks of the California company Dynalloy.

However, most bias solutions will involve a spring of one sort or another. To make a self-folding flap, anchor the ends of wire on the main side of the crease and attach the center of the wire very close to the crease on the flap. If you try to wrap a coil using only pliers and a dowel you will almost certainly hurt yourself.

FLEXINOL® Actuator Wires | DYNALLOY, Inc. Makers of Dynamic Alloys

If you’re looking for a fun spring which will stretch out in your hands, then flexiol back to being a spring if you heat it up, look for Kellogg’s Research Wiire Nitinol. Alternatively, guitar strings are made from the same material. Actuator wire is made from an alloy called Nitinol, and marketed under a number of brand names including Flexinol, BioMetal, and Muscle Wires.

The crimp bead holds onto the wire mechanically and also makes it possible to solder the ends for robust electronic connections. Education How making is transforming learning.

This is great and a wonderful price if flexjnol just want some muscle wire for some kit you’re building. This second application is exactly what happens in the operation of the gripper. Sign up for the Make: One of the most dramatic mechanisms is the curling mechanism where you simply sew nitinol to the paper.

How-To: Work with Shape-Memory Alloy

Yet another magical sculpture is the Robotany project by Jill Coffin, John Taylor, and Daniel Bauen in which the branches of a living tree are made to sway when someone walks by.

Please try your search again later. For these and other mechanisms, check out these projects from a recent paper electronics workshop.

Flecinol couple of convenient and readily accessible sources of springs for experimentation include rubber bands and the compression springs found in retractable ball point pens. In some applications it is possible to use the natural motion of the mechanism itself to provide the recovery force.

Flexinol is referenced in many books and research articles, and has been specified in a number of student and hobby-level robotics projects.


This mechanism uses the wire as a muscle to pull the flap. However, when heated to activation, they return to their preset shape. Please make sure that clexinol are posting in the form of a question.

You will also be receiving the weekly Make: The potential advantages to working with Nitinol actuators are significant. See and discover other items: Share your thoughts with other nuscle. Although it is possible to buy Flexinol pre-crimped, in most cases the hobbyist or student must crimp the wires themselves.

As with learning anything new, incorporating bias into your designs provides an opportunity for creative problem solving.

Introduction To FLEXINOL® Actuator Wire

Image Unavailable Image not available for Color: The properties of an actuator wire are highly dependent on the manufacture of the Nitinol and the muzcle of the wire. Roger Gilbertson, author of the Muscle Wires Project Book, recommends the N-scale rail joiners which are used to connect model railroad conductive track. Share Facebook Twitter Pinterest.

Jie put together this wonderful introduction to shape-memory alloy SMA for us. This stretching requires that a counter-balancing force be engineered into the project.

If you do choose to wind your own coils then be warned – you must use proper tools and wear eye protection even when working with very light gauges of music wire.
